2. Description of the Related Art

In recent years, with the rise of portable electronic devices havingcamera functionalities, the demand for an optical image capturing systemhas gradually been raised. The image sensing device of the ordinaryphotographing camera is commonly selected from a charge coupled device(CCD) or a complementary metal-oxide semiconductor sensor (CMOS Sensor).Also, as advanced semiconductor manufacturing technology enables theminimization of the pixel size of the image sensing device, thedevelopment of the optical image capturing system has gravitated towardsthe field of high pixels. Therefore, the requirement for high imagequality has been rapidly increasing.

The traditional optical image capturing system of a portable electronicdevice comes with different designs, including a two-lens or athree-lens design. However, the requirement for the higher pixels andthe requirement for a large aperture of an end user, likefunctionalities of micro filming and night view, or the requirement ofwide angle of view of the portable electronic device have been raised.But the optical image capturing system with the large aperture designoften produces more aberration resulting in the deterioration of qualityin peripheral image formation and difficulties of manufacturing, and theoptical image capturing system with wide angle of view design increasesdistortion rate in image formation, thus the optical image capturingsystem in prior arts cannot meet the requirement of the higher ordercamera lens module.

Therefore, how to design an optical image capturing system capable ofbalancing the requirement for higher total pixel count and quality ofthe formed image as well as the minimization of camera module byeffectively increasing the amount of admitted light and the angle ofview the optical image capturing system has become a pressing issue.

The aforementioned coordinatedirection of the tangential fan can be further divided into the positivedirection (the upper ray) and the negative direction (the lower ray).The transverse aberration at the longest operation wavelength passingthrough the margin of the aperture defines the difference between theimage position at the specific field of view where the longest operationwavelength passes through the margin of the aperture and strikes on thefirst image plane and the image position at the specific field of viewwhere the chief ray of the reference wavelength (for instance, thewavelength is 555 nm) strikes on the first image plane.

To evaluates the performanceof the specific optical image capturing system, we can utilize that thetransverse aberration at the 0.7 field of view (i.e., the 0.7 height ofan image HOI) where the longest operation wavelength passes through themargin of the aperture and strikes on the first image plane and thetransverse aberration at the 0.7 field of view (i.e., the 0.7 height ofan image HOI) where the shortest operation wavelength passes through themargin of the aperture and strikes on the first image plane (i.e., the0.7 height of an image HOI) both are less than 100 μm as a way of theexamination. Even further, the way of the examination can be that thetransverse aberration at the 0.7 field of view where the longestoperation wavelength passes through the margin of the aperture andstrikes on the first image plane and the transverse aberration at the0.7 field of view where the shortest operation wavelength passes throughthe margin of the aperture and strikes on the first image plane are bothless than 80 μm.

The arc length of any surface of a single lens within the maximumeffective half diameter affects the surface's ability to correct theaberration and the optical path differences between each of the fieldsof view. The longer the arc length is, the better the ability to correctthe aberration will be. However, difficulties may be found in themanufacturing process. Therefore, it is necessary to control the arclength of any surface of a single lens within the maximum effective halfdiameter, especially the ratio (ARS/TP) between the arc length (ARS) ofthe surface within the maximum effective half diameter and the thickness(TP) of the lens to which the surface belongs on the optical axis. Forinstance, ARS11 denotes the arc length of the maximum effective halfdiameter of the object side surface of the first lens. TP1 denotes thethickness of the first lens on the optical axis. The ratio between thetwo is ARS11/TP1. ARS12 denotes the arc length of the maximum effectivehalf diameter of the image side surface of the first lens. The ratiobetween ARS12 and TP1 is ARS12/TP1. ARS21 denotes the arc length of themaximum effective half diameter of the object side surface of the secondlens. TP2 denotes the thickness of the second lens on the optical axis.The ratio between the two is ARS21/TP2. ARS22 denotes the arc length ofthe maximum effective half diameter of the image side surface of thesecond lens. The ratio between ARS22 and TP2 is ARS22/TP2. The ratiobetween the arc length of the maximum effective half diameter of anysurface of the rest lenses in the optical image capturing module and thethickness (TP) of the lens to which the surface belongs on the opticalaxis may be deducted on this basis.

The arc length of any surface of a single lens within the height of halfthe entrance pupil diameter (HEP) particularly affects the surface'sability to correct the aberration and the optical path differencesbetween each of the fields of view at the shared area. The longer thearc length is, the better the ability to correct the aberration will be.However, difficulties may be found in the manufacturing process.Therefore, it is necessary to control the arc length of any surface of asingle lens within the height of half the entrance pupil diameter (HEP),especially the ratio (ARE/TP) between the arc length (ARE) of thesurface within the height of the half the entrance pupil diameter (HEP)and the thickness (TP) of the lens to which the surface belongs on theoptical axis. For instance, ARE11 denotes the arc length of the heightof the half the entrance pupil diameter (HEP) of the object side surfaceof the first lens. TP1 denotes the thickness of the first lens on theoptical axis. The ratio between the two is ARE11/TP1. ARE12 denotes thearc length of the height of the half the entrance pupil diameter (HEP)of the image side surface of the first lens. The ratio between ARE12 andTP1 is ARE12/TP1. ARE21 denotes the arc length of the height of the halfthe entrance pupil diameter (HEP) of the object side surface of thesecond lens. TP2 denotes the thickness of the second lens on the opticalaxis. The ratio between the two is ARE21/TP2. ARE22 denotes the arclength of the height of the half the entrance pupil diameter (HEP) ofthe image side surface of the second lens. The ratio between ARE22 andTP2 is ARE22/TP2. The ratio between the arc length of the height of thehalf the entrance pupil diameter (HEP) of any surface of the rest lensesin the optical image capturing module and the thickness (TP) of the lensto which the surface belongs on the optical axis may be deducted on thisbasis.

The optical image capturing system described above may be configured toform the image on the image sensing device which is shorter than 1/1.2inch in diagonal length; preferably, the size of the image sensingdevice is 1/2.3 inch. The pixel size of the image sensing device issmaller than 1.4 micrometers (μm). Preferably, the pixel size thereof issmaller than 1.12 micrometers (μm), and the best pixel size thereof issmaller than 0.9 micrometers (μm). Furthermore, the optical imagecapturing system is applicable to the image sensing device with aspectratio of 16:9.

The optical image capturing system described above is applicable to thedemand of video recording with above millions or ten millions-pixels(e.g. 4K2K or the so-called UHD and QHD) and leads to a good imagingquality.

The height of optical system (HOS) may be reduced to achieve theminimization of the optical image capturing system when the absolutevalue of f1 is larger than f4 (|f1|>|f4|).

When |f2|+|f3|>|f1|+|f4|, at least one lens among the second lens to thethird lens may have a weak positive refractive power or a weak negativerefractive power. The weak refractive power indicates that an absolutevalue of the focal length of a specific lens is greater than 10. When atleast one lens among the second lens to the third lens has the weakpositive refractive power, the positive refractive power of the firstlens can be shared by this configuration, such that the unnecessaryaberration will not appear too early. On the contrary, when at least onelens among the second lens to the third lens has the weak negativerefractive power, the aberration of the optical image capturing systemcan be slightly corrected.

Besides, the fourth lens may have negative refractive power, and theimage side thereof may be a concave surface. Hereby, this configurationis beneficial to shorten the back focal length of the optical imagecapturing system so as to keep the optical image capturing systemminimized. Moreover, at least one surface of the fourth lens may possessat least one inflection point, which is capable of effectively reducingthe incident angle of the off-axis rays, thereby further correcting theoff-axis aberration.

In the optical image capturing module provided by the presentdisclosure, the material of the lens may be made of glass or plastic.Using plastic as the material for producing the lens may effectivelyreduce the cost of manufacturing. In addition, using glass as thematerial for producing the lens may control the heat effect and increasethe designed space configured by the refractive power of the opticalimage capturing module. Moreover, the object side surface and the imageside surface from the first lens to the fourth lens may be aspheric,which may obtain more control variables. Apart from eliminating theaberration, the number of lenses used may be reduced compared with thatof traditional lenses used made by glass. Thus, the total height of theoptical image capturing module may be reduced effectively.

Furthermore, in the optical image capturing system provided by thepresent invention, when the surface of the lens is a convex surface, thesurface of the lens adjacent to the optical axis is convex in principle.When the surface of the lens is a concave surface, the surface of thelens adjacent to the optical axis is concave in principle.

The foregoingdriving module may be the voice coil motor (VCM) which is applied tomove the lens to focus, or may be the optical image stabilization (OIS)which is applied to reduce the frequency which lead to the out focus dueto the vibration of the camera lens in the shooting process.

At least one of the first lens, the second lens, the third lens, and thefourth lens of the optical image capturing system of the presentinvention may further be designed as a light filtering element with awavelength of less than 500 nm based on the demand. The light filteringelement may be made by coating film on at least one surface of that lenswith certain filtering function, or forming that lens with material thatcan filter light with short wavelength.

The image plane of the optical image capturing system of the presentinvention may be a plane or a curved surface based on the designrequirements. When the image plane is a curved surface (e.g. a sphericalsurface with curvature radius), the decrease of the required incidentangle to focus rays on the image plane is helpful.
